Interferon production by leukocytes in culture was investigated in nine severely marasmic infants and 31 well-nourished controls. The production of interferon was induced with Newcastle disease virus and assayed in Vero cells challenged with vesicular stomatitis virus. Marasmic infants produced significantly less interferon than controls. It is suggested that the finding may be the result of a lymphocyte defect induced by malnutrition and could help to explain the increased frequency and severity of viral diseases in this condition.

In human cell cultures the ability of poxviruses to rescue vesicular stomatitis virus from human interferon-induced resistance was significantly more efficient than the ability to rescue it from simian interferon-induced resistance. The sensitivity of the poxvirus to interferon was not related to its ability to rescue vesicular stomatitis virus.

Several viruses were categorized on the basis of their ability to spread from cell to contiguous cell and form plaques in the presence of antiviral antibody. Herpes simplex virus, cytomegalovirus, and vaccinia, measles, and foamy viruses were able to spread in the presence of neutralizing antibody, whereas coxsackievirus, encephalomyocarditis virus, vesicular stomatitis virus, mumps virus, and simian virus 5 failed to spread. A detailed study of one of these virus groups (simian foamy viruses) suggested that the ability of these viruses to spread from cell to cell in the presence of antiviral antibody, the failure of antiviral antibody and complement to lyse infected cells, and the poor induction and relative resistance of these viruses to the antiviral action of interferon contribute to the persistent nature of this infection.

The anticellular and antiviral effects of human leukocyte interferons were studied in vitro in the transformed human embryonic cell lines. RSa and RSb. The growth of these cells was inhibited and they began to deteriorate about 48 h after treatment with 500 units/ml of interferon. When interferon was washed out within 48 h, their growth recovered gradually. The effects of interferon on cell growth depended on the amount of interferon added per cell. A subline, named IFr, was isolated which grows in the presence of 2000 units/ml of interferon, whereas growth of vesicular stomatitis virus in these cells is suppressed by 10 units/ml of interferon, just as in the parent cells. The anticellular and antiviral effects of interferon on IFr cells are discussed in relation to cell surface receptors.

The effect of hydrocortisone on bovine interferon production in vitro was studied. Infectious bovine rhinotracheitis virus was used as an inducer. Interferon was assayed by the plaque-reduction method in bovine fetal kidney cultures, using vesicular stomatitis virus as challenge virus. Hydrocortisone decreased interferon production in bovine fetal spleen and peripheral blood leukocyte cultures. Hydrocortisone did not decrease interferon production by bovine alveolar macrophages, in 1 experiment. Properties of viral inhibitors were those of interferon.

The interferon-inducing ability of infectious bovine rhinotracheitis (IBR) virus was determined in tissue cultures of bovine origin inoculated with untreated and ultraviolet (UV) irradiated IBR viruses. Interferon was assayed by the plaque-reduction method in bovine fetal kidney (BFK) cell cultures, using vesicular stomatitis virus as challenge virus. Highest interferon concentrations were produced by cultures of bovine fetal (BF) spleen cells and aveolar macrophage cultures derived from adult cattle. Moderate interferon concentrations were produced by peripheral blood leukocyte (PBL) suspension cultures from adult cattle with serum-neutralizing antibodies against IBR virus. Cultures of PBL from 1 cow without detectable serum-neutralizing antibodies against IBR virus did not produce detectable interferon in response to IBR virus. Cultures of PBL from cattle with or without detectable serum-neutralizing antibodies against IBR virus produced interferon when stimulated with phytohemagglutinin (PHA). Low levles of viral inhibitors were detected infrequently in monolayer cultures of BFK and BF nasal mucosa inoculated with UV-irradiated IBR virus and in BF tracheal organ cultures inoculated with untreated IBR virus. Interferon was not detected in fluids collected from IBR virus-exposed monolayer cultures of primary and secondary BF lung, secondary BF tracheal mucosa, secondary BF liver, secondary BF adrenal, and PBL in the 4th and 7th passages. The antiviral inhibitors from BF spleen, bovine alveolar macrophage, and PBL cultures induced with IBR virus, as well as inhibitors from PBL cultures induced with PHA, had the usual properties of interferon.

Vesicular stomatitis virus forms discrete, microscopic plaques in stationary cultures of the WISH amnion cell line. Microplaque formation is rapid, reproducible, and easily quantitated, occurs at temperatures ranging from 33 to 40 degrees C, and does not require a semisolid overlay. WISH cells, however, are less sensitive to vesicular stomatitis virus than are chicken embryo, 3T6, or Vero cells. WISH amnion cells also are highly sensitive to the antiviral effects of human interferon, and a quantitative human interferon assay, based on vesicular stomatitis virus plaque reduction in WISH cells, is described. This interferon assay can be performed within 1 day, uses a liquid overlay medium, does not require a vital stain, is as sensitive as other methods that use diploid cell strains, and is performed in a microtiter system.

Chick embryo cultures treated with interferon yielded a biologically active RNA which, upon inoculation into chick embryo cells, created an antiviral condition in them. The level of vesicular stomatitis virus reproduction in such cells was 2-30% of that observed in the cells treated with control RNA. The maximum activity of the experimental RNA was seen 3 hours after the treatment with interferon.

Human cell culture-derived interferon was shown to inhibit human cytomegalovirus in vitro. A prototype strain, Davis, and six clinical isolates of cytomegalovirus were tested. All six isolates showed uniform susceptibility to interferon, exceeding that of the Davis strain by two- to fourfold. The latter virus was found to be 32 to 4 times less susceptible than the sensitive indicator, vesicular stomatitis virus. However, the laboratory finding of susceptibility to an antiviral material may not relate to its clinical effectiveness.

Defective interfering (DI) particles of vesicular stomatitis virus which contain covalently linked complementary [+]message and [-]anti-message RNA as a single-stranded ribonucleoprotein complex within the particle, are extremely efficient inducers of interferon. A single particle can induce a quantum yield of interferon. A single molecule of double-stranded RNA presumed to form, at least in part, on entry into the cell is thought to induce interferon synthesis. Conventional [-]RNA DI particles with the same polypeptide composition as [+/-]RNA DI particles fail to induce interferon.
